There was chaos for a few moments last night when Oscar history was made following the announcement of the wrong winner for Best Picture.

Famous leading man Warren Beatty began, "For Best Picture..." And then he looked at the envelope, paused and looked at Faye Dunaway. Dunaway laughed, called him impossible and announced La La Land as the winner. The stage immediately filled with the cast and crew - but also with Oscar producers.

When La La Land producer Jordan Horowitz was advised of the mistake, he explained, "I'm sorry, there's a mistake. Moonlight, you guys won best picture." Amid the confusion, producer Marc Platt reiterated, "This is not a joke. They read the wrong thing."

Horowitz flashed the card showing the winning movie to the audience. And with that, the Moonlight cast crew made their way to the stage.

Later, host Jimmy Kimmel joked, "Personally, I blame Steve Harvey for this." Harvey made history at the 2015 Miss Universe pageant when he misread the winner as Miss Colombia when it was actually Miss Philippines.
